Harness Sled Drag
intermediate · carry

Setup
Put the pulling harness over your shoulders and chest (or buckle a lifting belt if yours is the hip-strap type), cinch it snug and clip the line to a loaded sled behind you; with no harness, hold the strap in both hands.
Execution
- Load the sled, put the harness over your shoulders and chest and cinch it snug, or take the strap in both hands if you are pulling by hand.
- Lean slightly in the direction you are about to travel, whether forward or backward.
- Drive through your hips and knees with steady, controlled steps, keeping your torso stable.
- Keep your steps even in length; do not let the sled slow you into short choppy shuffles.
- Exhale on every step and keep breathing continuously across the whole distance.
- Cover the planned distance, then stop, unclip and rest before the next set.
- If your gym only has a short lane, do more shorter reps rather than fighting for one long distance.
Breathing
Breathe in rhythm with your steps, exhaling as each foot drives forward or back. If you have high blood pressure, heart disease, a hernia or you are pregnant, do not hold your breath: exhale as you drive each step and lighten the sled.
Quick cues
- Lean into the direction of travel.
- Even steps, don't shuffle.
- Hips and knees do the driving.
- Exhale on every step.
- Harness snug before you pull.
Common faults
Fault: Taking short choppy shuffle steps instead of full strides
Fix: Lighten the sled until you can take full, even steps.
Fault: Holding the breath through the effort
Fix: Exhale audibly on every step and cut the distance if the breathing breaks down.
Fault: The harness sitting loose so it rides up toward the neck or twists during the pull
Fix: Tighten the straps so they sit snug across the chest and under the armpits before the first step, and re-check them between sets.
Fault: Hunching the shoulders forward under the strain
Fix: Keep the chest tall and the shoulders down through the whole distance.
